Fox News published its debate criteria on Wednesday, stating that candidates: “Must place in the top 10 of an average of the five most recent national polls, as recognized by Fox News leading up to August 4th at 5 PM/ET. Such polling must be conducted by organizations that use standard methodological techniques.”

“The rules may be good for me personally, but they are not good for the process,” Carson wrote to members of the Republican National Committee.

He says that excluding voices from the debate would not make the Republican Party “bigger, better, and bolder.”

“We are blessed to have many qualified candidates running for President. More than a typical debate format can handle. Surely we can find a formal that allows every voice to be heard,” Carson stated.
